How is the bonding in NH3 and what does this entail for its electron-domain geometry and molecular geometry?

Nitrogen has atomic number 7; so, when neutral, it has 7 electrons . Those electrons are organized according to the Aufbau principle in an electronic configuration of 1s² 2s² 2p^...

Why does iodine have a higher boiling point than chlorine?

Iodine atoms have more electrons surrounding them than chlorine molecules. This results in Iodine having much stronger inter-molecular forces than chlorine, which require more energy to break, resulting i...

Potassium forms an ionic compound with sulfur. Describe what happens when atoms of Potassium react with atoms of sulfur. Give your answer in terms of electron transfer.

Electrons are transferred from potassium to sulfur. Two potassium atoms each lose one electron, and one sulfur atom gains both of the electrons lost by the potassium atoms. This results in K⁺ i...

If we burn 3 moles of carbon in air (as per the equation), what mass (in grams) of carbon dioxide will be produced? What volume will this gas occupy at standard temperature and pressure?

So firstly, we assume that the oxygen is in excess (i.e. the amount of oxygen reacting won't limit the amount of carbon that can react), so we know that exactly 3 moles of carbon will be burnt. Then, from...
